Abstract

The invention relates to a method for operating an internal combustion engine, wherein a crank case (2) of the internal combustion engine comprises ventilation (9) into the intake tract (10) of the internal combustion engine, characterized in that, during the outgassing of fuel from engine oil present in the crank case (2), the operating point of the internal combustion engine is modified such that said point does not fall below a predeterminable air/fuel ratio.
